350,651. Dressing fish. BISSET, J. D., Esplanade Sawmills, North Esplanade West, Aberdeen. April 16, 1930, No. 12004. [Class 28 (ii).] In a fish-skinning machine of the kind in which the fish is moved by a carrier, e.g. a rotary drum, into contact with the skinning knife, the carrier has sharp hooks, teeth or pins in a depression in its surface, so that the tail is impaled when it is inserted in the depression. A roller immediately behind the knife draws the skin from under the knife. As shown, the fish is rested, tail towards the drum 4, on a support 19, 20 which is reciprocated by a lever 21 actuated by a cam on the shaft 3 through the levers 24, 25. The part 19 is slidable relatively to the part 20 to which it is connected by a spring 27, so that when the support is moved towards the drum, the part 19 is first arrested by the drum whilst the movement of the part 20 continues, so that the tail is projected into the depression 10 into which the pins 11 are projected. The pins 11 are carried by a lever 12, 14 pivoted on a bracket 13 and are actuated by a cam 16 and a coil spring attached to the .arm 14. When the tail is positioned within the depression, it is forced on to the pins 11 by a presser 28 actuated by a cam on the shaft 3 through levers 30, 31. The knife 33 is a rigid blade adjustably mounted parallel to the drum axis, and is reciprocated by a crank and connecting-rod driven from the worm shaft 6. The drawing roller 38 is driven positively by a sprocket 39 and chain 40, the peripheral speed being greater than that of the drum. A pivoted scraper 43 is pressed resiliently against the drum by a rod 44 and a spring 47 which presses against the lever 21, and removes the skins from the drum.
